Title: Digital copying machine
Inventor: NISHITSUJI HIDEFUMI
IPC: H04N1/387
Filed: 1996-04-06
Abstract: PROBLEM TO BE SOLVED: To improve the operability, to shorten the copy time and to reduce the erroneous copy by printing the mark of 'X' at the designated coordinate of X and Y in the case of outputting a test copy. SOLUTION: Coordinates of a plurality of arbitrary point pair X and Y are inputted from an operating part 103. Assuming that these coordinates are within one rectangular range, an original is read by a scanner part 101. The mark of 'X' is incorporated to the read image in a memory part 102 based on the inputted coordinate data, and the copy is outputted. The machine has a mode for performing a test copy for previously confirming the designated range in the case of editing the rectangular designated range by designating the numerical values of coordinates of X and Y, and in the case of outputting the test copy, the machine prints the mark of 'X' on the designated coordinates of X and Y. Namely, by performing the test copy in a two-point designation editing mode and printing the mark of 'X' on the designated coordinates, the designated position can be confirmed in one operation.  Therefore, operations are simplified in comparison with the case of confirming the designated position by repeatedly copying the original, and the time for copying can be saved.
